I DEVICE FOR CLAMPINGBAR HOOKS.

Ne. 895,047. I

man, a citizen of the United States of Amer ica. residing in the city of St. Louis and State of Missouri, have invented certain new and useful Im rovements in Devices for Clamping-Bar I ooks, of which the following is a full, clear, ad exact description, reference being bad to the accompanying drawing, forming part of this specification.

My invention relates to a hook for suspending objects of various kinds, and more particularly intended for use in han ing large pieces of dressed meats, such as sides and quarters.

Hooks of the character described to which my invention more particularly relates, are usually employed upon racks containing pieces of tnnber of rectangular shape in cross section and these pieces of timber vary materially in thickness. so that plain hooks cannot be used satisfactorily in a universal tion of a hook having means connected therewith whereby the hook is rendered adjust-v able to fit supports of different dimensions. Figure I is a perspective view of my hook shown applied to a support. Fig. II is in part an elevation and in part a vertical section of the hook shown applied to a support. Fig. III is a side elevation of the grlpping member ofthe hook. Fig. IV is arear elevation of the gripping member. Fig. V is in part a section and in )art an edge elevation of the camlever mendwr of the hook. Fig. V I is a face view of the cam lever member. Fig. YII is a perspective view of the wedge shaped alining or hearing block.

- -In the accompanying drawings: A des g nates a support in the shape of a piece of timber to w nch my hook is shown applied.

1 designates the bow of the hook comprismg a depending front arm. a cross arm and a depending back arm '2. the latter of which is inclined forwardly and downwardly relative to the front arm. In the back arm 2 is a slot 3 that extends vertieallv or longitudinally of.

this against the innerface of the forwardly l mehned back arm 2 and IS preferably chan neled as shown, 1n order that it will straddleEI-- the back arm so as to direct the movement of the bearing block when said bearin block is raised or lowered against the inner face of said backarm. The outer face of the bearing block which bears against the inner face of the back arm is tapered, as most clearly seen in Fig. V II, while the op osite or inner face of the bearing block alfort s a perpendicular bearing surface f or a member to be here inafter more particularly mentioned. At the transverse center of the bearing block 4 is a non-circular or oblong aperture 5.

6 designates a gripping member that is provided with a. shank 7 of non-circular r oblong shape in cross section adapted to extend through the non-circular or oblong aperture in the bearing block 4 and the longitudinal slot'3 in the back arm 2. The shank 7 terminates in a screw threaded stem 8 that receives a nut 9 by which the shank is retained in the back arm .2. The body of the gripping member 6 is preferably in the shape of a disk having a forward face provided with serrations 10 or roughened in any desirable manner so that an etlicient gripping surface will be )resented toward the front arm of the hook how 1. At the rear of the body of the binding member 6 is one or more cams 11 preferably produced directly upon said. body, see Figs. III and I". The inner portion of the gripping member shank 7 that is in. immediate uxtaposition t0 the rear face of the body of the gri )ping member is cylindrical, as seen at 12, 19,8. III and IV.

13 designates a lever member which is in-' terposetl between the bearing block 4 and the body of the ripping member 6, and is rovided with a clrcular aperture 14 in which the cylindrical inner portion 12 of the gri )ing member shank 7 seats and on which t e lever member is rotated. The outer face of the lever member 13 is fiat and fits against the inner perpendicular face of the bearing block 4, while theinner face of saidlever member is provided with one or more earns 15 that oppose and are. adapted to cooperate with the cam or cams at the rear face of the gripping member 6. The lever member 13 is provided with a handle arm 16 by which the lever member may be rotated and it is also provided with a stop stud 17 that is adapted to strike against the bearing block ion 4 for the pn ose oi limiting the degree of rotation of sai lever member when the hook is not a phed to a support, thereb v keeping the hand e arm of the-lever member at the proper side of the hook in. order that when it is grasped and moved, the lever member may. be properly rotated for action upon the grip-' ping member 6.

' \Vhenmy hook is to be applied to'a suport, such for instance, as that illustrated in igs. I and II of the drawings, the bow of the hook is appiied to the support and the bearing block 4 tegether with the parts associated with it being raised are moved downwardly,

thereby causing them, including the gripping member 6, to be carried forwardly toward the su)port, due to the forward inclination of the hack arm 2. The handle arm 1.6 of the lever member 13 is then moved for the purpose of rotating said lever member upon the shank of the gripping member and through the medium of the cams on said lever member with the cams of the gripping member, the.

binding contact with the support to which it was carried under the influence of the lever member.

x I claim:

1. A hook comprising a bow having two arms, one of which is inclined towards the other and slotted, and clam )ing means slidably fitted to said incline arm, substantially as set forth.

2. A hook comprising a bow having two arms, one of which is inclined towards the othe a bintiiig member slidably fitted to said mclined arm, and a lever merrbcr for moving said binding member in a direction away from said inclined arm and towards the other "arm. substautiallv as set forth.

3. A hook comprising a bow having two arms, one of which is inclined towards the other, abimiing member movably fitted to said inclined arm, and a cam lever for moving said binding member, substantially as set forth. Y

4. A hook-comprising a bow having two arms, one of which is inclined towards the other, a binding member movably titted to said inclined arm and provided with a cam, and a cam lever for engagementwith the cam of said binding member and by which said binding member is moved relative to said inclined arm.

5. A hook comprising a bow having two arms, one of which is inclined towards the other, a binding member having a shank movably titted to said inclined arm, a block fitted to said inclined arm, and a cam member interposed between said binding member and inclined arm, substantially as set forth. 6. A hook comprising a bow having two arms, one of which is inclined towards the other, a binding member having a shank loosely fitted in said inclined arm, a block movably fitted to said inclined arm,'and a cam member inter )osed between said binding member and block, substantially as set forth. v

7. A- hook comprising a bow having 8. depending front arm, a cross arm, and a depending back arm; one of which depending arms is inclined towards the other deending arm, and vertically movable clamping means fitted to said inclined arm, substantiall v as set forth.
